Embodiment Construction

[0018] Such as figure 1 As shown, the intravascular ultrasonic dual-lumen microcatheter is composed of a vascular ultrasonic catheter 1 and a therapeutic microcatheter 2 connected in parallel with the vascular ultrasonic catheter 1 . The front end of the vascular ultrasonic catheter 1 is provided with a vascular ultrasonic catheter ultrasonic probe 6, and the end of the vascular ultrasonic catheter 1 is provided with a vascular ultrasonic catheter connecting plug 3, on the side wall of the vascular ultrasonic catheter 1, at a distance of 30-40 cm from the end of the vascular ultrasonic catheter ultrasonic probe 6. The position is provided with a guide wire outlet 4 of the vascular ultrasonic catheter; the front end of the treatment microcatheter 2 is provided with a guide wire outlet 5 of the treatment microcatheter, and a positioning mark 7 at the top of the treatment microcatheter is provided at a place 1mm away from the end 5 of the guide wire outlet of the treatment microca...

Abstract

The invention discloses an intravascular ultrasound double-cavity micro-catheter. The intravascular ultrasound double-cavity micro-catheter is characterized by being composed of a vascular ultrasound catheter and a treatment micro-catheter integrally in parallel connection with the vascular ultrasound catheter. The intravascular ultrasound double-cavity micro-catheter is small in outer diameter, a puncture lead wire is easily and synchronously brought into the lesion with the ultrasound double-cavity micro-catheter, and the ultrasound double-cavity micro-catheter effectively improves the controllability of the lead wire. In addition, the intravascular ultrasound double-cavity micro-catheter can show the tube wall and lesion characteristics. Due to the fact that two catheters are conjoined, when the lead wire puncture is performed under the vascular ultrasound guidance, the puncture lead wire and an ultrasound probe are relatively fixed in position, and relation of the guide lead wire and a target objective is easily confirmed, correct grasp of the puncture direction is facilitated, the success rate that the lead wire is fed into the true lumen can be greatly improved, and the operation achievement ratio can be improved.

Description

technical field [0001] The invention relates to a device for interventional treatment of chronic occlusion, in particular to an intravascular ultrasonic double-cavity microcatheter. Background technique [0002] Coronary heart disease is the first killer that endangers human health, and coronary chronic total occlusion (CTO) is the most serious type. CTO mostly refers to lesions with coronary artery occlusion for more than 3 months. The morbidity rate is high and the mortality rate is high. The lesions account for about 1 / 3 of all coronary angiography, but less than 8% receive percutaneous coronary intervention (PCI), accounting for about 15% to 30% of all PCI cases. The significance of successful PCI is that it can relieve the symptoms of angina pectoris, improve cardiac function, reduce the need for coronary artery bypass grafting (CABG), and prolong the life of patients. The biggest difficulty in the interventional treatment of CTO lesions is that it is difficult for th...
